According to the numbers I found on the Miata.Net and C5 registry:
Miata = .44Cd* x 17.7 frontal area = 7.788
C5 coupe = .29Cd x 21.7 frontal area = 6.293
* top down, as the 200mph guys say they intend to run. It's .36 with a hard
top.
That's 24% greater for the Miata, or 20% less for the Corvette, depending on
which side of the debate you're on. ;) Don't forget to square the velocity
before multiplying...

Yep, top speed is a "drag" race, but remember it is Cd*A. While the Miata
Cd
may kinda suck, I would suspect the cross sectional frontal area is quite a
bit
less than a Corvette.
